Abstract: Provided is an aqueous composition comprising (a) dispersed particles that comprise one or more ethylcellulose polymers and (b) one or more additives having molecular weight less than 220 g/mol, Hansen hydrogen bonding parameter greater than 11 MPa1/2 and less than 17.9 MPa1/2, Hansen total solubility parameter greater than 22 MPa1/2, and solubility in water greater than 2 g/L at 25° C. Also provided is a composition comprising particles having a coating, wherein said coating comprises 0-5% water by weight based on the weight of said coating, wherein said coating additionally comprises the ingredients (a) and (b).

Abstract: Disclosed is a conductive composition useful for the preparation of electrically conductive structures on a substrate comprising a plurality of metal particles, a plurality of glass particles and a vehicle comprising at least one cellulose derivative and at least one solid organopolysiloxane resin dissolved in a mutual organic solvent. The solid organopolysiloxane resin acts as adhesion promoter and assists in stably dispersing the metal and glass particles to avoid an agglomeration of such particles without degrading the rheological properties. From such conductive compositions uniform well adherent electrically conductive structures essentially free from defects in the form of cracks, bubbles or coarse particulates can be prepared on dielectric or semiconductor substrates such as silicon wafers in an efficient and cost-saving manner e.g. by screen printing, drying and sintering while inducing only low warping of the substrate.
