1. A plastisol composition, comprising:1) a copolymer composed of monomer components comprising: a) 0-90 wt.-% of a monomer selected from the group consisting of an acrylic acid alkyl ester with at least 3 carbon atoms in the alkyl radical, a methacrylic acid allyl ester with at least 2 carbon atoms in the alkyl radical, styrene and mixtures thereof; b) 10-99 wt.-% of monomer selected from the group consisting of methyl methylacrylate and ethyl acrylate; c) 1-20 wt. % of a hydrophilic compound of the formula (III): [EQU3] wherein: R1 is -CH3, -H; R2 is -CH2-; -(CH2) n-, wherein n is 2, 3, or 4; and wherein the -(CH2)n-group is branched or unbranched; R3 is -OH, -NH2, -N(R4)2; wherein R4 is -CH3, or -CH2-CH3; d) 0.01-1 wt. % of a crosslinking agent or a mixture of crosslinking agents; and e) 0-20 wt. % of other monomers that are radically polymerizable; wherein the relative amounts of components (a)-(e) add up to 100 wt. % of the monomer components; and 2) a plasticizer.
