DEFINITION

Classification: 8/446

Resist or reserve:

(under subclass 445) Processes for the production of patterns in a substrate by preventing coloration in local areas.

(1) Note. The resist composition may also include coloring matter for illuminating the parts of the pattern by coloring the same differently from the ground color.

(2) Note. The prevention of coloration may be accomplished by mechanical masks such as resinous or waxy materials; by chemical means preventing the formation or development of the color in local areas; or by modifying the characteristics of selected areas of the material, so that it does not have the same tinctorial properties as the untreated parts of the

material, as by mercerizing, immunizing, etc. The treated areas may have their affinity for certain types of dyes decreased but their receptivity for other types enhanced, as in the case of immunized or saponified areas, or by the application of so-called mordant-resists.

(3) Note. Silk screen printing is considered resist printing.

(4) Note. In the subclasses hereunder classification is only on the dye resisted.
