Abstract
A modified chlorinated polypropylene which has superior properties is obtained by the reaction of a chlorinated polypropylene having a molecular weight in the range of from 5,000 to 500,000 with a polyurethane having a molecular weight in the range of from 600 to 200,000. The modified chlorinated polypropylene exhibits excellent adhesion to various kinds of base film and a satisfactory performance with respect to such after-treatments as lamination, boiling and retort processes, and therefore is useful as a binder resin for printing ink or other coating compositions.
