Zusammenfassung: | A colour acceptor material for the thermal sublimation printing process with a carrier and a colour acceptor layer containing a copolymer of
a) 15-75% by weight of a vinylaromatic
b) 5-40% by weight of (meth)acrylonitrile
c) 10-70% by weight of (meth)acrylate ester with 4 to 18 C atoms in the alcohol radical
d) 0-30% by weight of further vinyl monomers
with the proviso that the glass transition temperature of the copolymer is more than 40 DEG C and the weight ratio of the components a:b is 1:1 to 4:1, is distinguished by high colour density and adequate image stability with minimum lateral diffusion. |
