A method that includes applying a color enhancing composition to a substrate and drying the color enhancing composition, where the color enhancing composition includes a carrier fluid; chromatically selective scattering particles having a particle size distribution as measured by (weight average diameter)/(number average diameter) of less than or equal to 1.1; and an absorber of visible light.

Method for changing color of substrate coating by application of stimulus

A method of revealing exposure of a substrate to an environmental stimulus includes exposing the substrate to the environmental stimulus, where the substrate includes at least one indicia, where each of the at least one indicia includes a plurality of chromatically selective scattering particles having a particle size distribution as measured by (weight average diameter)/(number average diameter) of less than or equal to about 1.1, and a colorant; and the at least one indicia exhibits a change in color in response to the environmental stimulus.

Printed indicator compositions

A method for changing the color of a substrate includes applying a color enhancing composition to the substrate to provide a first color; and applying a stimulus to the color enhancing composition to provide a second color; where the color enhancing composition includes a carrier fluid; chromatically selective scattering particles having a particle size distribution as measured by (weight average diameter)/(number average diameter) of less than or equal to 1.1; and an absorber of visible light.

Method for changing the color of a substrate coating by application of a stimulus

Color enhancing compositions for enhancing, changing and concealing the color of substrates to which the compositions are applied are provided. The compositions include chromatically selective scattering particles having small sizes and narrow size distributions. Inks, paints and other coatings made from the color enhancing compositions are also provided.

Color enhancing emulsions

A continuous polymerization process for producing reactive polymers comprises continuously charging into a first reaction zone at least one functional monomer and polymerizing the monomers to produce a first polymeric product having at least one functional group. This first polymeric product is then continuously directly charged into a second reaction zone together with at least one modifier reactant having a functional group that is complementary to the functional group of the first polymeric product. At least a portion of the modifier reactant reacts with at least one of the functional groups of the first polymeric product to produce a second polymeric product which incorporates at least a portion of the modifier reactant, such that the second polymeric product is a reactive polymer.

Process for continuous production of reactive polymers with in-line post-modification and products thereof

The present invention provides a high temperature continuous polymerization and condensation process for preparing a polymeric product. The process includes continuously charging into a reaction zone: at least one radically-polymerizable monomer having a radically polymerizable group and at least one condensation reactive functionality; and at least one modifying agent having a functional group capable of reacting with the condensation reactive functionality. The reaction zone includes at least one primary reactor, but may, and preferably does, contain a secondary reactor. The process further includes maintaining an effective temperature in the primary reactor to cause polymerization of the monomer and to allow at least a portion of the condensation reactive functionality to react with the functional group of the modifying agent.

Process for producing polymers by free radical polymerization and condensation reaction, and products related thereto

A process for preparing low molecular weight homomacromers and comacromers which includes (a) charging a reactor with (i) ethylenically unsaturated monomers selected from the group consisting of acrylic monomers or monoalkenyl aromatic monomers and (ii) if said ethylenically unsaturated monomer is not a thermally initiating monomer, a free radical polymerizable initiator, to form a polymerizable reaction charge. The reaction charge is heated during continuous mixing in the reactor to reaction temperature in the range from about 180&deg; C. to about 500&deg; C. for a residence time greater than 5 minutes to form the low molecular weight homomacromers or comacromers. If the residence time is 60 minutes or less, the reaction temperature is greater than 270&deg; C. and if the reaction charge is a mixture of acrylic monomer and monoalkenyl monomer and the residence time is 60 minutes or less then the reaction temperature is greater than 310&deg; C.
