Patent ID: 7423073

Claim:
An radiation curable resin composition, comprising: (a) about 5 to about 50 weight percent of a difunctional polymeric compound; (b) about 1 to about 10 weight percent of a photoinitiator; (c) about 1 to about 10 weight percent of a flexibilizer agent, wherein the flexibilizer agent has a molecular weight ranging from about 400 to about 10,000; and (d) about 30 to about 90 weight percent of a non-photoreactive solvent, wherein the weight percents are based on the total weight of the resin composition; wherein the flexibilizer agent is selected from the group consisting of: polypropylene gycol based polyols, polytetramethylene ether glycol, poly(oxypropylene) glycol, polybutadiene glycol, polyethylene adipate glycol, polyethylene propylene adipate glycol, polybutadiene adipate glycol, o-pththalate-1,6-hexanediol polyester polyol, diethylene glycol initiated caprolactone, trimethylol propane initiated caprolactone, neopentyl glycol initiated caprolactone, 1,4-butanediol initiated caprolactone, 1-6-hexanediol initiated caprolactone, polyethylene adipate glycol, polybutylene adipate glycol, diethylene glycol initiated caprolactone, and mixtures thereof.
