Abstract:
A film-forming composition selected from the group consisting of adhesives, inks and epoxide-based coatings, wherein said composition comprises:A) a polymer selected from the group consisting of (1) homopolymers and copolymers comprising repeating units of esters of acrylic and methacrylic acids; (2) said copolymers wherein a portion of the repeating units are derived from at least one acid selected from the group consisting of acrylic and methacrylic acids; (3) copolymers comprising repeating units of styrene and at least one member selected from the group consisting of esters of acrylic and methacrylic acids; (4) said styrene copolymers wherein a portion of the repeating units are derived from at least one acid selected from the group consisting of acrylic and methacrylic acids; (5) homopolymers comprising repeating units of vinyl acetate; (6) copolymers comprising repeating units of ethylene and vinyl acetate; and (7) homopolymers and copolymers comprising repeating units of organic compounds containing at least two epoxide groups per molecule; and B) from 0.1 to 40 weight percent of said composition of a plasticizer for said polymer, wherein said plasticizer comprises at least one benzoic acid ester exhibiting the formula PhCO(O)R1, where Ph represents a phenyl radical and R1 represents a linear or branched hydrocarbon radical containing 8 carbon atoms, and at least one additional benzoic acid ester selected from the group consisting of diethylene glycol dibenzoate and triethylene glycol dibenzoate, wherein the combined weight of all additional benzoic acid esters is from 0.5 to 2 times the weight of the ester corresponding to said formula.
