Embodiments of the invention provide a technique that effects spot gloss or gloss control and/or variations on one image without requiring clear inks. This is preferably accomplished by use of a multilayer printing process in which an image is first printed using a first set of color print heads and then cured, and in which the image is again printed using a second set of color print head, but where the image remains uncured for a predetermined interval to allow the ink drops applied to the media to spread and thus introduce a gloss effect.

Spot gloss and gloss control in an inkjet printing system

Embodiments of the invention have application in the field of inkjet inks. Additionally, the novel energy cure monomers and oligomers disclosed herein also have application more broadly in the field of energy cure inks and coatings.

Monomers and oligomers with application in energy curing chemistry

A thermochromic efficiency indicator for indicating efficiency of a temperature affector, and methods of making and using such a thermochromic efficiency indicator, whereby the thermochromic efficiency indicator comprises: a substrate; and a first indicia coupled to the substrate, the first indicia comprising a first thermochromic compound capable of undergoing a first thermochromic compound color change; wherein the first thermochromic compound color change indicates the temperature affector is below a first predetermined efficiency threshold.

Thermochromic efficiency indicator

A microencapsulated pigment including a leuco dye system is incorporated as one or more layers in a roll of adhesive tape. The tape is applied and may be rubbed by hand or another object to induce a color change. The change may serve as an indicator that the tape is well adhered for masking purposes in a painting operation, or to present a design where only selected portions of the tape are rubbed to induce the color change. The microencapsulated pigment may be constructed so that the color change is irreversible or reversible.

Pressure sensitive coating for image forming

Reversible thermochromic and photochromic ink compositions and markers, pens or writing instruments that use them are herein disclosed.

Reversible thermochromic and photochromic ink pens and markers

A microencapsulation process is improved by adding a stabilizing agent that contains one or more catalytic organo-metal oxide materials, such as metal soaps. This functions as a crosslinker by causing unsaturated bonds in the microcapsule walls to react, thereby stabilizing the microcapsules against the effects of additives to coatings that, otherwise, degrade the functionality of thermochromic or photochromic materials at the microcapsule core.

Stabilizing additives for thermochromic pigments

A new leuco dye produces a yellow color while demonstrating also exceptional light and thermal stability under light.

Yellow thermochromic dyes, inks composition and level indicators

A method is provided for making thermochromic pigments in microcapsules having unusually small particle sizes.

Small scale microencapsulated pigments and uses thereof

This invention relates to radiation curable ink compositions comprising one or more mono-functional monomers, optionally one or more oligomers, one or more antioxidants capable to react with peroxy radicals to generate radicals to propagate polymerization, and one or more photoinitiators comprising at least an acylphosphine oxide, wherein the ratio of the antioxidants to acylphpsphine is 1:1 to 1:20 by weight. The ink composition provides tack-free surface cure without requiring nitrogen or other inert gas during curing.
