摘要:
A dye acceptor element for thermosublimation printing comprising a support and a dye acceptor layer containing a graft polymer of an unsaturated copolyester as the graft base and a vinyl copolymer as the graft shell is distinguished by high color density, high sharpness, good image stability and a minimal tendency towards adhesion to than dye-donor lint.
摘要:
A dye acceptor material for thermosublimation printing comprising a support and a dye acceptor layer, characterized in that the dye acceptor layer contains a copolymer ofa) 15 to 75% by weight of an aromatic vinyl compound,b) 5 to 40% by weight (meth)acrylonitrile,c) 10 to 70% by weight (meth)acrylates containing 4 to 18 C atoms in the alcohol radical,d) 0 to 30% by weight other vinyl monomers,with the proviso that the glass transition temperature of the copolymer is above 40.degree. C. and the ratio by weight of component a) to component b) is 1:1 to 4:1, is distinguished by high color density and adequate image stability for minimal lateral diffusion.

Magnetorheological liquids, a process for producing them, their use and a process for producing polymer-coated magnetisable particles used in the magnetorheological liquids.
摘要:
Monodisperse crosslinked polymers prepared by seed/feed polymerization have less tendency to tack when a microencapsulated monodisperse crosslinked polymer has been used as seed. Compared with the seed used, the seed/feed polymer obtained exhibits substantially less broadening of the particle size distribution when microencapsulated seed has been used.
