The invention relates to the technical field of sublimation
transfer printing and discloses instant dry type sublimation transfer
digital paper. The instant dry type sublimation transfer
digital paper comprises perforated PP paper, a water absorbing and permeable layer, a
porous layer and a surface channel layer which are sequentially arranged from bottom to top; the
porous layer is made of interpenetrating network resin formed by crosslinking of
cellulose or
sodium carboxymethylcellulose or
starch and modified cationic
polyacrylamide, or formed by crosslinking of
polyacrylamide or
cellulose or
sodium carboxymethylcellulose and modified cationic
starch; on one hand, the interpenetrating network resin can swell to 'catch' a dye for quick ink absorption, and on the other hand, components of the resin are adjusted and the
network density is controlled to improve the water permeability, so that water molecules can quickly enter the water absorbing and permeable layer; and the perforated PP paper has excellent flexibility and
mechanical strength and is stable in size in the printing process, so that the problem of shrinkage, caused by weather, of the conventional paper base material is solved. The instant dry type sublimation transfer digital PP paper has the characteristics of being instant in
drying, quick in ink absorption, good in size stability and low in cost, and can meet the requirements for quick printing and efficient manufacturing at present.
