Кроме того у образца по примеру 6 после хранени  в нормальных услови х (18-25°С, 30-80%-на  относительна  влажность) 1 падает с 70 до 40%, что приводит к существенному снижению контраста отпечатка . Таким образом, термочувствительна  бумага по прототипу может хранитьс  при нормальных услови х ограниченное врем , а после влагоиспытаний на влагоустойчивость контраст отпечатка практически исчезает, тогда как образцы термочувствительной бумаги по описанию за вки приacid, and filler 3J. The coating has a high thermal sensitivity, but due to the initial color of e-hydroxyquinoline and especially its halogen derivatives and flow. color formation already at normal temperatures has a significant background. The main disadvantage of the coating is its low moisture resistance, which manifests itself in a sharp increase in the background and a decrease in the intensity of the imprint when storing the heat-sensitive material under conditions of increased visibility, which limits and hinders the practical use of the heat-sensitive material. The purpose of the invention is to increase the moisture resistance of the heat-sensitive coating. This goal is achieved by the fact that the thermosensitive coating of copying paper based on iron stearate (+3) and dienea oxyaromatic soybean, wax, polyvinyl alcohol, sodium stearate, stearic acid, ethylene diamine tetraacetic acid disodium salt and filler, is contained in an asylum-mantre sy mate rit maitre sy matere a non of a place ma tent sy material mate art clerk’s a heart art mate’s heart cushioned cushioned cushioned cushioned cushioned ethylenediaminetetraacetic acid and filler, sodium stearate, stearic acid, disodium ethylenediaminetetraacetic acid and filler; in the following ratio of components, wt.%: Dodecyl gallate .9-16 Iron stearate (+3) 19-34 Wax9-16 Polyvinyl alcohol 16-26 Sodium stearate 4-6 Stearic acid 4-7 Disodium salt ethylene diamine etrauksusnoy acid 4-8 NapolnitelOstaln invention is illustrated following the examples conductive. .

The temperature of the solution is reduced to 90-95 ° C and 20 parts by weight are added with stirring. 8% aqueous solution of polyvinyl alcohol, 50 weight, h. water and 3 wt.h, butanol. The composition is cooled to give 18-25 ° C. Suspension IT.

The resulting composition may be wounded without significant coloring up to 24 hours. The composition is applied onto the base paper and dried. The weight of the paper is | The composition of the semi-sensitive heat-sensitive coating on paper is shown in Table 1. Examples 2-5 The compositions of Examples 2-5 are prepared analogously to Example 1 from suspensions 1 and G1 and the quantities of polyvinyl alcohol solutions in Table 1 (8% ), disodium salt of ethylenediacNtetraacetic acid (7%) and filler paste (50%). Application and extrusion of compositions as in Example 1. The composition of the heat-sensitive coatings according to Example 2-5 is given in Table. 2. PREME R B (prototype). The composition of the heat-sensitive coating on paper, which is obtained according to the description of the prototype, includes, in May.%: Gland a (+3) 30. 8-hydroxyquinoline. 20 Polyvinyl alcohol 20 Wax. 10 Sodium stearate 1 Stearic acid 5 Disodium salt of ethylene diamine tetra Acetic acid 4 Kaolin 10 The intensity of the background and imprint reflection before (1p and IQ) and after moisture tests (, 98% relative humidity, 48 hours) (1 and ij, ) were measured with a light filter that corrected the spectral sensitivity of the photoelement of the spectrophotometer under the middle eye) .. as can be seen from the table. 2, sample 6 of temperature-sensitive paper according to the description of the prototype after moisture tests has 1 and 1 equal to 20 and 15%, which causes the imprint contrast almost completely disappears, and the samples of examples 1-5 after moisture tests retain a high contrast. In addition, the sample in example 6 after storage under normal conditions (18-25 ° C, 30-80% relative humidity) 1 drops from 70 to 40%, which leads to a significant decrease in the print contrast. Thus, the prototype thermosensitive paper can be stored under normal conditions for a limited time, and after moisture tests for moisture resistance, the contrast of the imprint practically disappears, while the thermosensitive paper samples according to the application
