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 a water-dispersible 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. This material is useful for the production of tamper proof laminates for identification purposes.
