Abstract

The present invention is related to sublimation transfer paper for cotton fabrics comprising sheet, printing layer and mixture resin layer containing polyethylenevinyl acetate, stearic acid and wax as a lubricant. More particularly, the transfer paper of the present invention has an enriched sublimation seepage force of dyes into the cotton fabrics and an improved surface touch feeling of cotton fabrics after transfer.

Claims
