ACRYLIC OLIGOMER OR ACTIVE ENERGY RAY-CURABLE COMPOSITION CONTAINING THE SAME AND ITS PRINTED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide an acrylic oligomer which has curability and abrasion resistance above those of DPHA, DTMP4A, and the like, and to provide an active energy ray-curable composition which uses the acrylic oligomer and is cured by the irradiation of UV light, electron beams, or the like.;SOLUTION: This acrylic oligomer (D) obtained by esterifying an acrylic acid polymer (A) represented by formula 1 : CH₂=CH-(COOCH₂CH₂)n-COOH [(n) is 0 or an integer, and has an average value of 0.1 to 3], a polyol (B), and a polybasic acid (C).;COPYRIGHT: (C)2006,JPO&NCIPI
