Mulching composite

A novel agricultural mulch is disclosed comprising a paper substrate having coated thereon on the top and bottom side film forming latexes resistant to water permeability. The superior paper mulch according to the invention is degradable but possesses most of the beneficial aspects of polyethylene-type mulches.

Heat-sensitive recording material

HEAT SENSITIVE RECORDING MATERIAL.

A high sensitivity thermal paper resistant to image erasure has a colour forming composition comprising a chromogenic material, an acidic developer material, a water insoluble hydrocarbon resin selected from poly- alpha -methylstyrene or alpha -methylstyrene/vinyltoluene copolymer, a thermal modifier and a binder. Preferably the thermal modifier is acetoacet-o-toluidine, diphenoxyethane, phenyl 1-hydroxy-2-naphthoate, diheptadecyl ketone or octadecanamide. The disclosed composition when thermally imaged is surprisingly resistant to image erasure and smearing attributable to fingerprint oils.

Thermally-responsive record material

ABSTRACT A novel thermally-responsive record material is disclosed comprising a support having provided thereon in substantially contiguous relationship an electron donating dye precursor and a fluorene bisphenol of the formula (I) wherein each R is independently selected from hydrogen and C1 to C8 alkyl, and a suitable binder therefor. The record material according to the invention when imaged resists fade when contacted with certain environmental challenges including oils, solvents, and elevated temperatures, all of which can be encountered in the environments of use of these record materials.

Heat-sensitive recording material

Thermally responsive record material

Thermally-responsive record materials are described containing a "complex" material formed from interactions at high pH between zinc stearate and ammonia and/or zinc stearate, ammonia and zinc oxide. The use of these materials in thermally-responsive sheets improves thermal image response and/or improves resistance to thermal image decline upon exposure to elevated temperature.

Thermally-responsive record material

A navel thermally-responsive record material is disclosed comprising a support having provided thereon in substantially contiguous relationship an electron donating dye precursor and a succinimide of the formula wherein n is an integer from 1 to 3 wherein each R is independently selected from hydrogen and C1 to C8 alkyl, and a suitable binder therefor. The record material according to the invention when imaged resists fade when contacted with certain environmental challenges including oils, solvents, arid elevated temperatures, all of which can be encountered in the environments of use of these record materials.
