Document Type and Number:
WIPO Patent Application WO/2019/049626
Kind Code:
A1
Abstract:
Provided are a composition having little variation in terms of particle diameter of a dispersed infrared radiation-absorbing pigment and a method for producing same as well as a film, an optical filter, a layered product, a solid state imaging device, an image display device and an infrared radiation sensor obtained using the composition. The composition contains an infrared radiation-absorbing pigment, an acid or a base capable of undergoing neutralization or salt exchange with the infrared radiation-absorbing pigment, an acidic or a basic resin and a solvent, wherein the acidic resin is contained in cases where the composition contains the acid, the basic resin is contained in cases where the composition contains the base, and formula A or formula B is satisfied, with the pKa value of the acid being denoted by pKa1A, the pKa the value of a conjugated acid of the base being denoted by pKa1B, the pKa value of the acidic resin being denoted by pKa2A, and the pKa value of a conjugated acid of the basic resin being denoted by pKa2B, and the method produces this composition. The film, the optical filter, the layered product, the solid state imaging device, the image display device and the infrared radiation sensor are obtained using the composition.
Formula A: pKa1A > pKa2A
Formula B: pKa1B < pKa2B
