Abstract:
A method for coating a printed surface of a plasticized vinyl chloride polymer layer optionally having an embossed surface, comprising;a) applying a coating composition to said polymer layer,b) evaporating at least a portion of said solvent system, andc) concurrently and/or subsequently to evaporating, cross-linking said coating composition at an elevated temperature wherein said coating composition comprises:1) a solvent system consisting essentially of water, one or more alkyl alcohols of 1 to 8 carbon atoms, and one or more alkylene glycol alkyl ethers,2) an amino resin cross-linking agent being alkylated benzoguanamine, alkylated urea, or alkylated melamine fomaldehyde resin, or combinations thereof, and an acid catalyst therefore,3) a polyester resin miscible with said solvent system and said amino resin, which is capable of being cross-linked by said amino resin cross-linking agent and said acid catalyst, and4) optionally a silicone glycol and wherein at least 90 mole % of the dicarboxylic acids of said polyester are saturated dicarboxylic acids, at least 95 mole percent of said acids are straight chain carboxylic acids having from 4 to 8 carbon atoms, and at least 95 mole percent of the polyol of said polyester is bis(hydroxymethyl) cyclohexane.
