A composition comprising a photopolymerizable epoxy-containing material which is useful to provide a hermetically sealed liquid crystal display cell. The photocured seal is chemically resistant to the contents of the liquid crystal cell. Adhesion of the photopolymerizable epoxy material to the glass

A composition comprising a photopolymerizable epoxy-containing material which is useful to provide a hermetically sealed liquid crystal display cell. The photocured seal is chemically resistant to the contents of the liquid crystal cell. Adhesion of the photopolymerizable epoxy material to the glass plates of the liquid crystal cell is improved by addition of glycidoxypropyl triethoxy silane or its precondensate.

A photopolymerizable, adhesive, sealant composition comprising: (a) cationically polymerizable epoxide with a functionality of at least 1, and (b) an organic aromatic onium catalyst comprising an aromatic adduct of (1) a diaromatic, triaromatic, or tetraaromatic organoatomic cation of a Group Va, VI

A photopolymerizable, adhesive, sealant composition comprising: (a) cationically polymerizable epoxide with a functionality of at least 1, and (b) an organic aromatic onium catalyst comprising an aromatic adduct of (1) a diaromatic, triaromatic, or tetraaromatic organoatomic cation of a Group Va, VIa, or VIIa atom and (2) an anion; said onium catalyst being represented by the formula: [Figure] wherein R2 is an aromatic group at least as electron withdrawing as benzene, R1 is an alkyl or alkenyl group, A is a Group Va, VIa, or VIIa atom, X is an anion, n is a positive whole integer of at least 2 up to the valence of A plus one, a is 0 or a positive whole integer up to the valence of A minus one, and n plus a is equal to the valence of A plus one and wherein at least two of said R2 groups are bonded to A, and (c) an adhesion-aiding amount of glycidoxypropyl triethoxy silane or its precondensate.
