PURPOSE:To obtain an adhesive agent having excellent uniform sprayability to a substrate by using a mixture composed of spacer particles and adhesive particles having a specific relation between triboelectrostatic charge voltages. CONSTITUTION:This powder adhesive agent is the mixture composed of the spacer particles and adhesive particles having the relation ¦A-B¦>=30muc/g when the triboelectrostatic charge voltage of the spacer particles to iron powder is designated as Amuc/g and the triboelectrostatic charge voltage of the adhesive particles as Bmuc/g. The spacer particles to be used are exemplified by spherical org. polymer particles, spherical particles of an inorg. oxide, carbide or nitride, or the ground matter of fibers. The adhesive particles to be used are exemplified by spherical particles or shapeless particles of epoxy, polyolefin, ionomer, polyes ter and acrylic. The uniform distribution ratio of the spacer particles and adhe sive particles is obtd. in any part of the sprayed surface by using the adhesive agent in common use as the spacer for the liquid crystal electrooptic element in the above-mentioned manner. |
