Description

-ell v r) ^ 22' 842o COMPOilTION FOR TREATMENT OF CINE FILM MATERIALS The
invention relates to compositions for the treatment of cine film materials and can be used in cinematography and chemical-and-photographic industry at the final stage of production or prior to use of cine films.
When run in motion-picture projectors and during multiple rewindings the cine film materials experience considerable surface wear because of mechanical damage in both the photosensitive layer and film support, brought about by frictional force arising during the movement of materials through film gates, in cassettes etc.
In the world practice, in order to improve anti-friction properties of cine film materials, it is quite common to treat them with different compositions reducing their friction coefficient, thus increasing the service life of these materials and quality of motion picture demonstration.
Treatment of cine film materials in order to improve their antifriction properties is also carried out in the process of their chemical-andphotographic treatment.
In so doing, the above treatment of cine film materials is performed at the final stage of chemical-and-photographic processing.
Known in the art is a composition for treatment of cine film materials, consisting of a silicom and a chlorine-containing solvent taken in a 1: 300 ratio (DD, C, 22953).
As a silicon this composition contains a mixture of halogenosilane and polysiloxane in a 1: 10 ratio, and as a chlorine-containing solvent - a mixture of fluorotrichloromethane and tetrachloromethane in a 1: 2 ratio.
This composition is used for the improvement of the antifriction properties of cine film materials.
Said composition is proposed for the application to f.i- 1.
nished cine film materials manually during their rewinding. This is associated with an unfavourable effect of toxic components of the composition on the organism of the operator attending, and requires additional equipment for safety of operation.
Besides. the manual application of the Composition does not provide for a high labour productivity.
Known in the art is a composition for the treatment of cine film materials, also used for improving their antifric the USSR, tlon properties (Transactions of NIKPI Goskino of 1. collection of papers, issue 118, 1984, Moscow. A.A.Gorina and L.K.Klimova "Siliocne lubricant for motion-iccture prints and its effect on their service life". pp.41-53).
This prior-art composition contains polydimethylsiloxane or polymethylhydride siloxane as a silicone, and perchloroethylene as a solvent with the following component ratio in wt. %0:
silicone 0.1-0.2 solvent the balance "his composition is applicable only for the treatment of cine film materials with the use of special costly equipment ultrasonic cleaning machines. As the composition contains a toxic solvent, it is necessary to provide a plant for its recovery and regenerationg as well as additional safety measures when working with this composition.
Known in the art is a multicomponent composition for the treatment of cine film materials, which is an oil-in-water >.
emulsion. The composition contains a sillicone-polyorganosiloxane with trimethylsiloxane end groups having 103 - 105 mm2/8 viscosity, a wetting agent (e.g. saponin, potassium alkenyl succinate, alkylarylaulphonic acids), an emulsifier k'e.g, salts of acylamino-g alkylaulphamidecarboxylic'acids) and water in the fjllowing component ratio in wt, %: polyorganosiloxane with trimethyl- siloxane end groups and 103-105 mm2/s viscosity wetting agent emulsifier k 0.017-0.070 0.018-0.045 0.010-1111,.060 wat e r the balance (DE, C, 2509534). - 3aid composition is used for treatment of cine film materials with developed image at the final stage of cherrical-andphotugraphic treatment prior to the entry of these materials into the cabinet drier of the processing machine.
When this co=position i.A used, it is necessary to treat the cine film materials during a long time interval (from 0.5to 2 minutes this f act making it unfit for use in modern highspeed developing machines without a drastic change in their design.
Said composition requires the use of specialized equipment for its preparation (mixers, homogenizers, mills), besides, it is unstable and, when applied to cine film materials, some defects like spots9 tails, blushing may be formed on their surface.
Besides, a rise in the ambient temperature results in emulsion breaking and polydimethylsiloxane precipitation, thus clogging the developing machine communications.
It is an object of this invention to improve the anti friction properties of cine film materials.
This object is accomplished due to the fact that the com.erials treatment contains a silicone position for cine film ma41.1 and water. as the silicone component it contains a block copolymer of the general formula [R SiO - [R2 J 3 0.51 a Sal b [RS:L01.51 cXdy /Formula I/ wherea= 0-2;b=0-150; c - 0; 1; dwO-3; the values of a, b,, c cannot be zero simultaneously; R m alkyl (C, C 4); phenyl; X = (OC2H4)m (OC3116)n 0, where Z a hydroxy, alkoxy (C 1 - c 4) or acetoxy group; m =6 - 40; n - 0 40; and Y is absent or Y m [RSi 1 [RS:L 0] k 1 Oi k2 (CH2)3 (OC2H4)m 1 (X2H4)m2 1 1 OC 3H6)n 1 (X3 H6)n2 1 1 Z Z2 where Z 1 and Z2 - hydroxy, alkoxy (C, - c 4) or acetoxy group; k 1 + k2 - 1 - 50; k, or k2 may be equal to 0; m, =6 - 50; M2 w 6 - 40; ni = 0 - 50; n2 - 0 - 40; with the following component ratio in wt. %: block copolymer kuh2)3 0.05-0.5 water the balance.
In some separate cases it is desirable that the compoai tion according to the invention for treatment of cine film ma terials should contain additionally a polyester of the gene ral formula A 1 (OC 2 H 4)p (OC 3 H 6)q 0A2 /Formula - I- I/ where A,, A2 - hydrogen, alkyl (Cl-C4), acetyl; p - 6-40, q = 0-40; with the following component ratio in wt. block copolymer polyester 0. 050-0. 5 0.002-0.3 water the balance.
The use of a block copolymer as a silicone in the hereinproposed composition makes it possible to simplify the method of p?eparing and the formulation of the composition for treatment of cine film materials.
The use of a composition based on the above block copolymer with the proposed quantitative ratio of the components makes It possible to improve the antifriction properties of cine film materials treated with this composition. Assuming the friction coefficient of untreated cine film materials to be 100 %, that of the materials treated with the hereinproposed composition is reduced by 85 % at the photosensitive side, and by 73 % at the film support side of the cine film materials.
There is a simultaneous reduction of time for the treatment of cine film materials with the herein-proposed composition down to 0.5 - 30 s.
The decrease of the block copolymer percentage below 0.05 wt. % leads to an insufficient improvement of the antifriction properties of cine film materials treated with the herein-proposed composition. Thus, with the percentage of the block copolymer in the herein-proposed composition equal 'm 0.04 wt. %, the friction coefficient of cine film materials after the treatment with the composition is lower than that of the untreated materials by 68 % at the photosensitive side, and by 62 % at the film support side of the cine film material.
It is inexpedient to raise the block copolymer percentage in the proposed composition above 0.5 wt. %, since it does not lead to a further improvement in the antifriction properties of cine film materials treated with this composition. Thus, with the content of the block copolymer in the proposed composition being 0.51 wt. %, the friction coefficient of cine film materials after their treatment with the composition is reduced compared to that of the untreated cine film material by 85 % at the photosensitive side, and by 73 % at the film support side of the cine, film material.
The incorporation of a polyester at the following component ratio in wt. %:
block copolymer polyester 0.050-0.5 0.002-0.3 water the balance promotes faster dissolution of the block copolymer in water, thus simplifying and expediting the preparation of the compo- ant when high-molecular sition, this being especially import block copolymers are used, The introduction of a polyester in quantity above 0.3 is inappropriate, since the time of the block copoly-mer dissolution in water remains the same.
The introduction of a polyester in quantity below 0.002 does not facilitate the dissolution of the block copolymer in water.
The herein-proposed composition for treatment of cine film materials is prepared by simple mixing of the components without heating. Accorcling to the invention, the composition is atable during storage, convenient in use (since it is an 1 aqueous solution and does not foul communications; it is nontoxic).
The treatment of cine film materials with the present composition does not impair the physical and mechanical properties of these materials (such as impact strength, curling) and does not produce a destabilizing effect on color image dyes under severe temperature and moisture storage conditions of color cine film materials.
The herein-proposed composition is prepared by mixing the block copolymer, or its mixture with a polyester, with water at room temperature in the ratios specified above.
A better understanding of the present invention will be had from the following examples of the proposed composition for the treatment of cine film materials.
