2 gas laser output 1 w beam diameter 150 microns resultantly deep black images were obtained 5 parts of fluoran derivative obtained in example 1 was dissolved in 100 parts of isopropylated naphthalene the resultant solution was dispersed in 350 parts of warm water 50 u00b0 c containing 25 parts of pigskin gelatin having an isoelectric point of 8 and 25 parts of gum arabic dissolved in it to obtain an emulsion 1000 parts of warm water was added to the emulsion the mixture was adjusted to ph 4 with acetic acid and cooled at 10 u00b0 c 10 parts of 25 aqueous solution of glutaraldehyde was added to it to solidify capsules the capsule containing coating composition was coated on one surface of a base sheet of 45 g m 2 in the weight of 5 g m 2 on dry basis and an acceptor coating composition comprising 20 parts of zinc 3 5 di u03b1 methylbenzyl salicylate 80 parts of kaolin and 30 parts of styrene butadiene copolymer emulsion solid content 50 dispersed in 200 parts of water was coated on another surface of the base sheet in the weight of 5 g m 2 on dry basis to obtain a pressure sensitive record material middle sheet several of the pressure sensitive record material were piled in the manner as the capsule coated layer was closed to the acceptor coated layer pressed with driving a pen to obtain black color images on the acceptor coated surface the color images were obtained with a rapid color development and in a deep color immediately after press and the color change and discoloration were not appreciated when exposed to sunlight.
