COATING OF PAPER Abstract of the Disclosure A coating composition comprising granules of unmodified rice starch dispersed in a latex of a flexible polymer was applied to bank note paper. Only the surface fibres of the paper were penetrated, the body fibres being left unaffected. The paper had improved resistance to soiling, humidity and deterioration due to folding. It also had improved detail and fine line fidelity when sub- jected to the conventional printing operation. There was no discernible change to the appearance of the paper and it retained its characteristic crackle.
