Abstract

PURPOSE: To manufacture a laminated sheet having excellent punchability, by using a resin varnish obtained by compounding a curable unsaturated resin with a plasticizer composed of a reaction product of tung oil, maleic anhydride and an alcohol.
CONSTITUTION: 1mol of maleic anhydride is made to react with pref. 1W2mol of of tung oil, and then with an alcohol (pref. those having polymerizable unsaturated group, e.g. allyl alcohol) to obtain a plasticizer. The amount of the alcohol is pref. 0.5W1.5 times mole of the tung oil. Pref. 10W20pts.wt. of the plasticizer is added to 100pts. of a curable unsaturated resin such as unsaturated polyester resin to obtain a resin varnish. A proper number of substrate sheets impregnated with the varnish are laminated, and cured to obtain the objective laminated sheet.
