摘要: A novel imaging process is disclosed comprising preparing microcapsules having an elongation of less than 1%, adhering the microcapsules to a substrate then imagewise rupturing certain of said microcapsules upon selective application of a thermal energy input comprising a .DELTA.T of at least 115.degree. C. per 1 millisecond. The process makes use of novel microcapsules polymerized at a temperature of from 65.degree. C. to 100.degree. C. which are heat resistant yet heat fracturable upon application of a thermal pulse.

摘要: A novel record material is disclosed comprising a substrate bearing microcapsules having nonmeltable walls. The microcapsules contain a chromogen or developer and a photosensitive composition internal thereof, said microcapsules undergoing a change in viscosity upon exposure to actinic radiation. The walls of the microcapsules have an elongation of not more than 1%, and the record material is resistant to heat, measured by not producing any substantial color when placed in a 150.degree. C. oven for one minute. Surprisingly, the record material however is capable of forming a color upon application to the record material of a point source energy input comprising a .DELTA.T of at least 115.degree. C. per one millisecond.
