PURPOSE: To obtain a primer compsn. excellent in adhesion property to an inorg. base body, by compounding a specified thermoplastic elastomer, a colloidal inorg. oxide and a mixture solvent of a protophilic solvent and an OH group-contg. solvent. n CONSTITUTION: The mixture solvent (C) is prepared by mixing a protophilic solvent (a) having ≤100°C boiling temp. (under atmospheric pressure) such as acetone and an OH group-contg. solvent (b) having ≤125°C boiling temp. (under the atmospheric pressure) such as propanole. The compsn. of the purpose is obtd. by compounding 0.5 to 10 pts.wt. of one or more kinds of thermoplastic elastomers (A) soluble by ≥10 wt.% in the component (a), 1 pt.wt. of one or more kinds of colloidal inorg. oxides (B) selected from among collodial oxides of Si, Cr, Ti, Zr having <400 Å grain size, and the component (C) comprising 5 to 30 pts.wt. of the component (a) and 1.0 to 10 pts.wt. of the component (b) to 1 pt.wt. part of the component (A). n COPYRIGHT: (C)1989,JPO |
