PURPOSE:To improve fixability at low temp., anti-offsetting property and blocking resistance by rendering a specified range of modulus of dynamic shearing storage elasticity to a binding resin at each of specified temps. CONSTITUTION:The binding resin has a 1X10<5>-5X10<6>dyn/cm<2> range of modulus G' of dynamic shearing storage elasticity at 1Hz frequency at a temp. T1 expressed by equation I and 1X10<3>-5X10<4>dyn/cm<2> range to the resin at a temp. T2 expressed by equation II. A styrene-(meth)acrylate copolymer such as a styrene-butyl acrylate copolymer or polyester resin is preferably used as the binding resin. In the equations I, II, TR is the temp. ( deg.C) of a hot roll and TA is atmospheric temp. ( deg.C). Fixability at low temp., anti-offsetting property and blocking resistance are improved. |
