PURPOSE:To obtain a compsn. having resilience, good film formability, good adhesiveness and excellent acid resistance by incorporating a specific resin and the specific sodium or potassium salt of 4, 4'-diazide stilbene-2, 2'-disulfonic acid as essential components into said compsn. CONSTITUTION:This compsn. contains the resin expressed by the formula I and the sodium or potassium salt of 4, 4'-diazide stilbene-2, 2'-disulfonic acid expressed by the formula II as the essential component. In the formula I, X is an org. acid when X exists, Y is the carbon-carbon double bond-contg. group expressed by -OCH2CH=CH2, etc., n is >=10 integer, j is the number to satisfy 0<j<1, t denotes 0 or 1 integer. In the formula II, Z denotes a sodium atom or potassium atom. |
