PURPOSE:To obtain the subject composition, safe for fire and capable of providing a good stringy material by blending specific amounts of an acrylic ester- based resin with an aqueous solution and an aerosol propellant composed of specified two kinds of liquefied gases. CONSTITUTION:The objective composition is obtained by blending (A) 15-35wt.% acrylic ester-based resin (e.g. a methacrylic acid ester resin, an acrylic acid ester resin and/or a copolymer resin thereof) with (B) 15-33wt.% aqueous solution (preferably an aqueous solution with 15-30wt.% alcohol content) and (C) a propellant composed of (i) 15-50wt.% liquefied gas (preferably dimethyl ether, monochlorodifluoroethane, etc.) to be a true solvent and (ii) 50-85wt.% liquefied gas (preferably liquefied petroleum gas, tetrafluoroethane, etc.) to be a poor solvent. |
