ADHESIVE FOR WATCH DIAL, AND WATCH DIAL

摘要

PROBLEM TO BE SOLVED: To provide an adhesive for watch dials, which can be used on even a resinous dial having low heat resistance and by which a three-dimensional large hour digit can be stuck to the watch dial without using an unnecessary member such as a sheet so that the stuck hour digit is not peeled off even at high temperature and to provide a watch obtained by using the adhesive for watch dials.SOLUTION: The adhesive for watch dials comprises A) an acrylic copolymer having three or more hydroxyl groups in one molecule thereof and 20°C or lower melting point, B) an isocyanate derivative having the reactive equivalent weight of 3-95% of that of the acrylic copolymer and two or more isocyanate groups in one molecule thereof and C) a solvent having 5-100 parts weight with respect to the total amount of the A) component and the B) component and 220°C or lower boiling point. The watch is produced by using the dial prepared by using a diluted solution containing the adhesive of the amount equal to or more than 50 wt.%.
