Patent ID: 7538145

Claim:
A composition, comprising: (a) curable monomer; (b) at least one photoinitiator that initiates polymerization of said curable monomer; and (c) phase change agent that provides the composition with an increase in viscosity of at least four orders of magnitude, from a first temperature, said first temperature being from 50° C. to 130° C., to a second temperature, said second temperature being from 0° C. to 70° C., wherein the second temperature is at least 10° C. below the first temperature, wherein the phase change agent is selected from the group consisting of hydrogenated castor oil, 1,10-decanediol, 1,12-dodecanediol, hydroxyl-terminated polyethylene waxes, 1-tetradecanol, 1-pentadecanol, 1-hexadecanol, 1-heptadecanol, 1-nonadecanol, 1-eicosanol, 1-tricosanol, 1-tetracosanol, 1-pentacosanol, 1-hexacosanol, 1-heptacosanol, 1-octacosanol, 1-nonacosanol, 1-tricontanol, 1-dotriacontanol, 1-tritriacontanol, 1-tetratriacontanol, 2-tetradecyl 1-octadecanol, 2-hexadecyl 1-eicosanol, 2-octadecyl 1-docosanol, 2-nonadecyl 1-tricosanol, 2-eicosyl tetracosanol, 1,8-octanediol, 1,9-nonanediol, 1,13-tridecanediol, 1,14-tetradecanediol, 1,15-pentadecanediol, 1,16-hexandecanediol, 1,17-heptadecanediol, 1,18-octadecanediol, 1,19-nonadecanediol, 1,20-eicosanediol, 1,22-docosanediol, 1,25-pentacosanediol, and mixtures thereof.
