Abstract

1,264,170. Papermaking; pressure-sensitive record sheets. RANSBURG ELECTROCOATING CORP. 18 June, 1969 [18 June, 1968], No. 30888/69. Headings D2A and D2B. Record paper is made on the papermaking machine by depositing microcapsules containing dye precusor on the wet web by an electrostatic process. Preferably they are deposited on the felt side of the web while it is still on the wire, but reference is also made to deposition between or in place of sets of press rolls or between the last press and the dryer, and to application to the wire side of the web. The microcapsules may be applied together with or after dry particles of watersensitive binder, e.g. starch or polyvinyl acetate. The other side of the web may be coated with a coreactant, e.g. clay, by adding it with the size at the size press.
