DEFINITION

Classification: 427/146

(under the class definition) Processes directed to the production of a base with a coating which is (1) transferable as a continuous or a discontinuous film; (2) transferable from the base to another surface by an inscribing operation, when not provided for in another class; or (3) capable of producing a copy of printed or s:graphic subject matter by heat or chemical reaction.

(1) Note. Included herein or in subclasses indented hereunder are processes for making decalcomania and paper supports therefor, embossing foils, carbon paper, typewriter ribbons, and carbonless paper.

(2) Note. This and indented subclasses also include patents directed to producing a stack or pile of sheets or bases provided with transferable coatings where no structure is defined in addition to a stack or pile.

(3) Note. Processes directed to producing a coating which is intended to be completely transferred from its supporting base in the area contacted by the inscribing instrumentality are within the scope of this and indented subclasses.

(4) Note. This subclass includes patents directed to exposing a normally colored but invisible coating by transparentizing or removal of the material which conceals the colored composition or ingredient.

(5) Note. Inscribing is used in the broad sense to include hand-held writing instruments (e.g., pens or pencils) or machines (e.g., typewriters). (6) Note. Production of coated paper specifically adapted to receive designs or coatings to form transfers is provided for in this subclass and indents herein under.

(7) Note. This subclass will take combinations of making and using a transfer where the transferred material is liquid or powder. For transfer of a solid layer see Class 156, subclasses 230+.

(8) Note. This subclass does not include the production or use of a roller, web or other transfer machine which is not an article of manufacture as a base with a transfer coating.

(9) Note. Ordinary uncoated paper copy sheets are not copy sheets within the scope of this and indented subclasses when claimed alone.

(10) Note. Processes for making carbon paper and typewriter ribbons are examples of transferable coated papers within the scope of this and indented subclasses.
