Opaque Coating Composition

The process is for developing an opaquing composition. Such is employed for covering imperfections, e. g., pin holes, scratches, voids, etc., present in glue silver photographic patterns or vacuum deposited metal opaque films.

The process consists of combining equal parts of a mixture, designated below as Part A, with an equal part of a mixture, designated Part B. PART A

% composition

No. Material by Weight 1 HYSOL 2O38 34. 00

2 Titanium Dioxide (TITANOX AMO) 7. 14

3 Carbon Black (KOSMOBILE #77) 7. 14

4 Toluene 34. 00

5 MODAFLOW .72

6 Xylene 17.00

PART B

% Composition

Ingredient No. Material by Weight

1 HYSOL 3466 37.4

2 Toluene 62.6

The combined mixture can then be applied to the patterns or the films by brushing or spraying. Next, the patterns or films are dried for a 30 minute interval at room temperature. Then the patterns or films are cured for a 2 1/2 hour interval at a temperature of 140 degrees F. *HYSOL, TITANOX, KOSMOBILE and MODAFLOW are tradenames of Houghton Laboratories, Inc., Titanium Pigments Corp., United Carbon Co., and Monsanto Chemical Co., respectively.
