Disclosed herein is a pressure-sensitive recording material including such a sheet excellent in the durability and definition of the recorded images transcribed on another sheet, which is produced by the process comprising the step of applying the microcapsules encapsulating minute particles of a pigment dispersed in a solution of an adhesive and optionally, an oil-soluble colored dyestuff dissolved in the solvent onto a supporting material such as sheet, and a process for producing the same.

Pressure-sensitive recording material

Disclosed herein is a printing material set for preparing bar-code labels by pressure-sensitive printing method comprising (a) a printing tape of a film carrying on the inside surface thereof the microcapsules containing the minute particles of a pigment dispersed in a solution of an adhesive component dissolved in an organic solvent as a core material, and (b) a bar-code label tape comprising bar-code label papers having an adhesive on the undersurface thereof and a stripping tape carrying the bar-code label papers and being removably attached to the adhesive, the printing tape being superposed on the bar-code label tape, the microcapsules facing the uppersurface of the bar-code label tape.

Printing material set for preparing bar-code labels by

The electric device according to the present invention has as its constituents the insulating materials and elements comprising films of synthetic resin, for instance, polypropylene, impregnated with 1-phenyl-2-ethylphenylethane and/or 1-phenyl-2-isopropylphenylethane. According to the present invention, insulating oils having favorable compatibility with the film of synthetic resin such as polypropylene and favorable affinity to metals and having low viscosity have been provided, and in addition, electric devices excellent in properties of withstanding a high voltage and dielectric properties in a broad range of temperature from a low temperature to a high temperature have also been offered.

Electric device comprising impregnated insulating materials and electric
