A method of solvent fusing thermal images is disclosed herein an inert gas is bubbled through a liquid solvent to vaporize the solvent. The solvent temperature is controlled. The vaporized solvent fuses the image.

Solvent fusing of thermal printer dye image

Fogging by the condensation of water vapor on optically transmissive surfaces of optical devices, such as the lens of goggles, is prevented by means of a transparent hydrophylic polymer integrated therewith and disposed in the moisture laden environment. A perfluorosulfonic acid polymer, such as is sold under the trademark Nafion by Du Pont, is used. The polymer is attached to the surface of the lens which faces the wearer of the goggles, as by being laminated to the lens. The polymer provides a transparent regeneratable dessicant, even though it is attached to the non-permeable lens, and removes water before it can condense as droplets to fog the lens. There also may be characteristics of the hydrophylic polymer other than that of a dessicant which is significant in the fog prevention (e.g. contact angle of water droplets on the surface).
