Visible image-shaped regions of colloid material in a thin layer are transferred from a temporary support to a permanent support by means of a chemically hardenable adhesive applied as a liquid coating between the colloid material to be transferred and the permanent support and allowed to harden so that the temporary support can be peeled away. The visible image-shaped regions of the colloid material can form part of an overall layer or the non-image portions of such layer can be removed in advance. A preferred colloid layer is constituted of solid hydrophobic thermoplastic polymer particles dispersed in a hydrophilic binder in a weight ratio greater than 1:1 and a preferred hardenable adhesive is an epoxy resin in liquid state having a viscosity of 8,000 to 20,000 cp. which is applied to at least the pattern on the temporary support carrying the colloid layer thereon and permeates the colloid layer so that upon hardening of such resin, improved resistance to wear, humidity and heat is imparted to the colloid. |
