BILDEMPFANGSMATERIAL ZUR VERWENDUNG IN DIFFUSIONSUEBERTRAGUNGS-UMKEHRVERFAHREN.

摘要

Image-receiving material for use in diffusion transfer reversal processing comprising a polyvinyl chloride resin support coated with a hydrophilic waterpermeable layer comprising a proteinaceous colloid and an ionogenic polyester-polyurethane wherein isocyanate groups still present in its structure have reacted with an ionogenic compound containing at least one active hydrogen atom and a carboxylate or sulphonate salt group. The use of said material for the production of tamper proof laminates for identification purposes.
