Abstract: An aqueous crosslinkable coating composition that includes a PU polymer and a vinyl polymer bearing carbonyl groups (i.e., a carbonyl-functional vinyl polymer) and/or latex polymer. The composition also preferably includes carbonyl-reactive amine and/or hydrazine functional groups.

Abstract: An apparatus and method for preparing a stain to match a target color of a selected substrate (e.g., wood species). The apparatus and method may include a computer system and hardware or software to display to a user of such system an image array depicting a target image of a stained building material and a plurality of images of colored stains as applied to the same or other building materials.

Abstract: The present invention relates to color matching and, more specifically, an apparatus and method for preparing a stain to match a target color of a selected substrate (e.g., wood species). In one embodiment a system is provided that comprises (i) a computer (e.g., a stand-alone PC or a networked computer), (ii) hardware and/or software to store a database of stain records, (iii) hardware and/or software to create or load spectral data (e.g., a digital image) of a target sample, and (iv) hardware and/or software to display images and/or process spectral data. The system preferably facilitates the selection of a desired stain, and in preferred embodiments may also include hardware and/or software to dispense colorant agents and/or vehicles to create the desired stain.

Abstract: An apparatus and method for preparing a stain to match a target color of a selected substrate (e.g., wood species). The apparatus may include a computer and hardware and/or software to store a database of stain records, create or load spectral data (e.g., a digital image) of a target sample, and display images and/or process spectral data. The apparatus may facilitate stain selection, and may also dispense colorant agents and/or vehicles to create stains. The apparatus may be used in a “manual” mode (whereby a human compares database and target images and makes a selection); an “automatic” mode (whereby the computer suggests a match based on the selected substrate); or a “combination” mode (whereby the computer suggests a match and the user can then compare the suggested match with various images to achieve a final selection).
