摘要

As for topic of this invention, the released paper and use of the silane functionality poly- vinyl alcohol in the undercoat medicine for the exfoliation film being, the said silane functionality poly- vinyl alcohol, 1 - 30 mols % ratio, is the 1- alkyl vinyl ester where 1 - 6, the alkyl group of 1 kinds or plural kinds of carboxylic acid 1 - 6 has C atom have C atom I) a) vis-a-vis all polymer, the vinyl ester of 1 kinds or plural kinds of alkyl carboxylic acid of non ramification chain or ramification chain where 1 - 18 have C atom, bC) these and you make the copolymerization possible other comonomer polymerize radical) 0.01 - 10 mols % with the silane content ethylene unsaturated monomer, and case of 1 kinds or plural kinds, and you are obtained by saponifying the polymer which is obtained because of this, 75 - 100 mols % perfection saponification or the part which possesses degree of hydrolysis it is the use which at least contains the silane content poly- vinyl alcohol of 1 where the vinyl ester copolymer which is saponified is designated as the foundation kinds.
