Abstract
Thermosensitive recording material for use in thermal printing, which is composed of a coating composition applied on a support, which coating composition comprises (a) a chromogenic compound, (b) an organic acid, (c) a water-soluble binder containing a carboxyl group and having a softening point of 200.degree. C or higher, (d) a filler, (e) a metal salt of a higher fatty acid and (f) a wax, said recording material having a Bekk surface smoothness of 100 to 500 seconds.
Claims19
A thermosensitive recording material composed of a coating composition applied as a single layer on a paper, synthetic resin film or textile cloth support, which coating composition comprises (a) a chromogenic compound, (b) an organic acid which melts or vaporizes at room temperature or higher and reacts with the chromogenic compound to develop color, (c) a water-soluble binder containing a carboxyl group and having a softening point of 200.degree. C. or higher, (d) an infusible filler, (e) a metal salt of a higher fatty acid, and (f) a wax, the weight ratio of (a) to (b) being from 1/1 to 1/20, the amount of (c) being 15 to 50% by weight based on the total solids content of the composition, the amount of (d) being 30% to 300% by weight based on the total weight of (a) and (b), the total amount of (e) and (f) being 10% to 200% by weight based on the total amount of (a) and (b), the weight ratio of (e) to (f) being from 1/10 to 10/1, said recording material having a Bekk surface smoothness of 100 to 500 seconds.
