Abstract of the Disclose This invention relates to a process for coating the surface of a shaped article of cellulose hydrate with a layer of polymer material which comprises applying to the surface of a shaped article in the gel state and based on cellulose hydrate, a liquid layer of an aqueous solu- tion of a chemically modified protein obtained by mixing an aqueous alkaline protein solution with an aqueous solution of N-methylol- acrylamide or N-methylol-methacrylamide or of the alkoxy derivatives thereof of aliphatic alcohols with 1 to 8 carbon atoms, particularly of organic, tetrafunctional, doubly unsaturated compounds of the general formula Image in which R1 and R2 are hydrogen or an alkyl group with 1 to 6 carbon atoms, and R3 is the group -(CH2)n-, in which R4 is an alkyl group with 1 to 18 carbon atoms, subjecting the liquid mixture to a dwell time, heating the coated shaped article, and wetting the shaped article. The invention also relates to a shaped article of cellulose hydrate having a coating of protein thereon.
