摘要:
The suspension developer contains, in an electrically-insulating carrier liquid, a pigment and a block copolymer comprising a block of polymerized vinylaromatic compounds and a block of polymerized dienes the double bonds of which have been partially or completely reacted with alkyl mercaptans. The developer is distinguished by its high dispersion stability, small particle size and uniform particle size distribution.

摘要:
A thermosensitive recording material contains a mono-, oligo- or polysaccharide and a catalyst in one or more binder layers arranged on a transparent support. A black-and-white image with high optical density, good grey step reproduction, great sharpness and good stability is formed when the material is heated imagewise, e.g. by means of a thermohead.
摘要:
In a dye acceptor element for the thermal dye sublimation printing process, containing a support and a dye acceptor layer consisting of a continuous phase and at least one disperse phase the dispersed phase is formed by a partially or completely cross-linked 1,3-dienehomo- or -co-polymer which has a solubility parameter of from 8 to 12 (cal/cm.sup.3).sup.1/2. The disperse phase makes up 20 to 90% by weight of the sum of the continuous and disperse phases. The dye acceptor element is distinguished by high resolution, high brilliance and good long term stability.

摘要:
The suspension developer contains as a toner polymer-sheathed pigment particles in an electrically insulating carrier liquid. The sheath of the pigment particles is formed by precipitation polymerization from various (meth)acrylates, a cross-linker and, optionally, a vinyl or vinylidene monomer. The developer has an outstanding dispersion stability which does not change during use or storage.
