MODIFIED STARCH AND COATING SLIP COMPRISING THE SAME

摘要

A modified starch and a coating slip containing the same are described. The modified starch is characterised in that it has a degree of substitution in respect of carboxyl groups of 0.005-0.070, a degree of substitution in respect of cationic, hydrophobic groups, which contain a hydrocarbon chain having 7-20 carbon atoms, of 0.008-0.080, and that an aqueous solution of the modified starch has phase separation in the range 0-100.degree.C, preferably about 30-60.degree.C.
