Abstract (en)
[origin: EP0850786A2] A hot melt transfer material (I) consists of a porous hot melt layer (II) applied to a support (III). (II) consists of fine thermoplastic polymer particles and a thermoplastic polymer based binder containing anchored microporous particles with a spontaneously wettable surface. Also claimed is the preparation of (I) by coating a dispersion containing particles, dissolved binder, precipitating agent and a solvent having a vapour pressure higher than that of the precipitating agent, onto the support (III) and drying with associated phase inversion and pore formation.
