1. A curable composition comprising a polythiol; at least one unsaturated compound comprising two or more carbon-carbon double bonds, carbon-carbon triple bonds, or a combination thereof; and a dye compound represented by formula: wherein R is hydrogen or alkyl;X is alkylene;Y is a bond, ether, thioether, amine, amide, ester, thioester, carbonate, thiocarbonate, carbamate, thiocarbamate, urea, thiourea, alkylene, arylalkylene, alkylarylene, or arylene, wherein alkylene, arylalkylene, alkylarylene, and arylene are optionally at least one of interrupted or terminated by at least one of an ether, thioether, amine, amide, ester, thioester, carbonate, thiocarbonate, carbamate, thiocarbamate, urea, or thiourea; andZ is an acrylate, a methacrylate, an acrylamide, a methacrylamide, a styrenyl, a terminal alkenyl, or a thiol. 2. The curable composition of claim 1, wherein Z is an acrylamide, an acrylate, or a methacrylate. 3. The curable composition of claim 1, wherein Y is a bond, —O—, —O—C(O)—, —O—C(O)—NR1—, or alkylene optionally at least one of interrupted or terminated by at least one ether, ester, carbonate, or carbamate. 4. The curable composition of claim 3, wherein —X—Y—Z is —CH2CH2—O—C(O)—CH═CH2, —CH2CH2—O—C(O)—C(CH3)═CH2, or —CH2CH2—O—C(O)—C(CH3)2NHC(O)—CH═CH2. 5. The curable composition of claim 1, further comprising a free-radical initiator. 6. The curable composition of claim 5, wherein the free-radical initiator is a photoinitiator. 7. The curable composition of claim 5, wherein the free-radical initiator is a thermal initiator. 8. The curable composition of claim 1, wherein the polythiol is monomeric. 9. The curable composition of claim 1, wherein the polythiol is oligomeric or polymeric. 10. The curable composition of claim 9, wherein the polythiol is an oligomer or polymer prepared from components comprising a dithiol and a diene or divinyl ether. 11. The curable composition of claim 1, wherein the at least one unsaturated compound comprises two carbon-carbon double bonds, and wherein the curable composition further comprises a second unsaturated compound comprising three carbon-carbon double bonds. 12. The curable composition of claim 1, further comprising at least one of silica, carbon black, calcium carbonate, or aluminum silicate. 13. The curable composition of claim 1, wherein the at least one unsaturated compound comprising two or more carbon-carbon double bonds, carbon-carbon triple bonds, or a combination thereof comprises at least one of a diene, a diyne, a divinyl ether, a diallyl ether, or an eneyne. 14. The curable composition of claim 1, wherein the terminal alkenyl includes at least three carbon atoms. 15. The curable composition of claim 1, wherein Y is a bond, —O—C(O)—, or alkylene optionally at least one of interrupted or terminated by at least one ether or ester. 16. The curable composition of claim 1, wherein R is hydrogen. 17. A crosslinked polymer network comprising: a polythiol crosslinked with at least one unsaturated compound comprising two or more carbon-carbon double bonds, carbon-carbon triple bonds, or a combination thereof; anda dye compound represented by the following formula covalently incorporated into the crosslinked polymer network: wherein R is hydrogen or alkyl;X is alkylene;Y is a bond, ether, thioether, amine, amide, ester, thioester, carbonate, thiocarbonate, carbamate, thiocarbamate, urea, thiourea, alkylene, arylalkylene, alkylarylene, or arylene, wherein alkylene, arylalkylene, alkylarylene, and arylene are optionally at least one of interrupted or terminated by at least one of an ether, thioether, amine, amide, ester, thioester, carbonate, thiocarbonate, carbamate, thiocarbamate, urea, or thiourea; andZ is an acrylate, a methacrylate, an acrylamide, a methacrylamide, a styrenyl, a terminal alkenyl, or a thiol, wherein Z has been reacted to form a covalent bond in the crosslinked polymer network. 18. A sealant comprising the crosslinked polymer network of claim 17. 19. A method for indicating curing in a curable composition, the method comprising: providing the curable composition of claim 1, wherein the dye compound is present in the composition in an amount sufficient to provide the composition with a first absorbance at a wavelength in a range from 400 nanometers to 700 nanometers; andallowing the composition to cure to provide a cured composition, wherein the cured composition has a second absorbance at the wavelength that is different from the first absorbance. 20. A method of stabilizing a curable composition comprising a polythiol and at least one unsaturated compound comprising two or more carbon-carbon double bonds, carbon-carbon triple bonds, or a combination thereof, the method comprising adding to the composition a dye compound of the following formula: wherein R is hydrogen or alkyl;X is alkylene;Y is a bond, ether, thioether, amine, amide, ester, thioester, carbonate, thiocarbonate, carbamate, thiocarbamate, urea, thiourea, alkylene, arylalkylene, alkylarylene, or arylene, wherein alkylene, arylalkylene, alkylarylene, and arylene are optionally at least one of interrupted or terminated by at least one of an ether, thioether, amine, amide, ester, thioester, carbonate, thiocarbonate, carbamate, thiocarbamate, urea, or thiourea; andZ is an acrylate, a methacrylate, an acrylamide, a methacrylamide, a styrenyl, a terminal alkenyl, or a thiol, in an amount sufficient to reduce a viscosity increase of the curable composition relative to a comparative composition that is the same as the curable composition except that it does not contain the dye compound.
