COMPOSITION FOR TONER ADHESIVE LAYER AND HIGH MOLECULAR FILM FOR COPY HAVING TONER ADHESIVE LAYER USING THEREOF

摘要

PURPOSE: A composition for a toner adhesive layer which is able to form a toner adhesive layer with an excellent toner adhesive strength, electrostatic preventing property and heat-resistance and a high molecular film for copy having a toner adhesive layer using thereof are provided. CONSTITUTION: A composition for a toner adhesive layer comprises: (i) 6-10 wt.% of a thermoplastic copolymer containing methylmethacrylate unit and butylacrylate unit; (ii) 3-5 wt.% of a thermohardened polymer which is able to crosslink the thermoplastic copolymer; (iii) 3-5 wt.% of an electrostatic preventing agent which has more than one functional group selected from the group consisting of alkoxy group, hydroxy group, amine group and conjugate double bond; (iv) 0.05-1 wt.% of a thermostabilizing agent; and (v) the remainder of water. The high molecular film for copy comprises: (i) a high molecular base material film; and (ii) the toner adhesive layer comprising 35-65 wt.% of a thermoplastic copolymer containing methylmethacrylate unit and butylacrylate unit; 15-30 wt.% of a thermohardened polymer which is able to crosslink with the thermoplastic copolymer; 15-30 wt.% of an electrostatic preventing agent which has more than one functional group selected from the group consisting of alkoxy group, hydroxy group, amine group and conjugate double bond and 0.3-6 wt.% of a thermostabilizing agent.
