An apparatus is for glossing a sheet having a thermoplastic resin on the surface thereof. The thermoplastic resin is capable of forming a film which imparts gloss upon the application of heat. The apparatus includes a sheet support, a first pair of rollers for feeding the sheet onto the sheet support wherein the resin side of the sheet is away from the sheet support, heating elements, a blower for blowing air through the heating elements to generate hot air which is blown onto the sheet, and a second pair of cold rollers for receiving the sheet after passage over the sheet support.

Hot air apparatus for glossing sheets

Disclosed is a developer sheet useful in forming reproductions having a glossy finish, or in forming transparencies comprising:

Developer sheet useful in providing transparencies or reproductions

Method for polymerizing a monomer suspended in water which comprises: Preparing a polymerization mixture of a water immiscible, liquid, ethylenically unsaturated monomer, a polyisocyanate and an oil soluble free radical initiator, dispersing said mixture in a solution of water and a surfactant, and effecting polymerization of said monomer.

Microsuspension polymerization

A developer sheet comprising a support having a layer of a color developer on the surface thereof, said color developer being capable of reacting with a substantially colorless electron donating color former to produce a color image and being an acrylic or methacrylic polymer having pendant developer moieties (e.g., hydroxy aromatic or aromatic acid moieties such as salicylic or phthalic acid moieties) which are preferably metallated (e.g., zincated) or being the polymeric reaction product of vinyl salicylic acid or salt.

Vinyl developer resins

A developer sheet comprising a support having a layer of a color developer on the surface thereof, said color developer being capable of reacting with a substantially colorless electron donating color former to produce a color image and being an acrylic or methacrylic polymer having pendant developer moieties (e.g., hydroxy aromatic or aromatic acid moieties such as salicyclic or phthalic acid moieties) which are preferably metallated (e.g., zincated) or being the polymeric reaction product of vinyl salicylic acid or salt.
