Abstract
A heat activatable printable material for the ink-jet printing process comprising a support and a heat-activatable polymer layer. The polymers of the polymer layer is a mixture of nonionic water soluble polyethylene oxide polymers with the general formula H—[—O—CH2—CH2—]nOH, and an aliphatic polyester type polyurethane resin. The polymer layer is ink-jet printed and heat activated to adhere to a substrate with the support remaining on the polymer layer after adhesion of the polymer layer to the substrate.
Claims31
A heat activatable ink-jet printable material comprising a support and a heat-activatable ink-jet printable polymer layer wherein the polymer of the polymer layer is a mixture of
- (i) about 40 to 70 weight percent based upon the total polymers in the polymer layer of nonionic water-soluble polyalkylene oxide polymer having the general formula H—[—O—CH2—CH2—]nOH wherein the degree of polymerization n is in the range of about 1,000 to 200,000;
- and
- (ii) 35 to 60 weight percent based upon the total polymers in the polymer layer of at least one additional thermoplastic polyurethane polymer having a softening point of about 50 to 70° C.;
- and
- wherein said polymer layer is located on and remains on the support after heat activation.
A method of applying an ink-jet printed material to a substrate comprising:
- providing an ink jet printable material comprising a support and a heat-activatable ink-jet printable polymer layer wherein the polymer of the polymer layer is a mixture of
- (i) about 40 to 70 weight percent based upon the total polymers in the polymer layer of nonionic water-soluble polyalkylene oxide polymer having the general formula H—[—O—CH2—CH2—]nOH wherein the degree of polymerization n is in the range of about 1,000 to 200,000;
- and
- (ii) 35 to 60 weight percent based upon the total polymers in the polymer layer of at least one additional thermoplastic polyurethane polymer having a softening point of about 50 to 70° C.;
- ink-jet printing the polymer layer;
- applying the printed polymer layer to a substrate;
- heat activating the polymer layer to adhere the polymer layer to the substrate;
- and
- retaining the support on the polymer layer to cover the polymer layer after it is adhered to the substrate.
