<P>PROBLEM TO BE SOLVED: To provide a photopolymerizable inkjet ink which satisfies both reduction in viscosity and improvement in hardenability without having a problem for skin sensitization. <P>SOLUTION: The photopolymerizable inkjet ink includes: at least one of a compound group (A) which is negative for skin sensitization and at least one of a compound group (B) which is negative for skin sensitization. The compound group (A) consists of caprolactone-modified dipentaerythritol hexaacrylate, polyethoxylated tetramethylol methane tetraacrylate, ethylene oxide-modified bisphenol A diacrylate, caprolactone-modified hydroxy pivalic acid neopentyl glycol diacrylate, polypropylene glycol diacrylate [CH<SB POS="POST">2</SB>=CH-CO-(OC<SB POS="POST">3</SB>H<SB POS="POST">6</SB>)n-OCOCH=CH<SB POS="POST">2</SB>(n≈12)], hydroxyethyl acryl amide, trimethylol propane trimethacrylate, and tricyclodecane dimethanol dimethacrylate; and the compound group (B) consists of ethylene oxide-modified phenolacrylate, isostearyl acrylate, ethylene oxide-modified trimethylol propane trimethacrylate, stearyl methacrylate, and glycerin dimethacrylate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
