1. A method for edge coloring/edge painting of leather substrates, comprising the steps of:
burnishing the edges of the leather substrate;
application of adhesion promoter on the edges of the leather substrate in the range 0.1-0.3 mm, and drying for a period of 1-2 min at room temperature;
application of adhesion promoter on a transfer film;
spraying or pouring of the liquid edge paint on the transfer film to convert it into solid edge colour paint as a sticker film; and
transfer of the edge paint sticker film to the edge of the leather substrate followed by application of heat 110-130° C. and pressure 60-70 PSI kg/cm2 and removal of the sticker film,
wherein the edge paint is a liquid which when poured on the transfer film with adhesion promoter is converted to solid coloured sticker film and is transferred to the edge of leather substrate on application of temperature and pressure.
