Patent ID: 7291672

Claim:
A paste composition comprising: (i) a polyurethane resin which comprises: (a) a recurring unit represented by the following formula (1): wherein A is a group (divalent group) given by removing OH groups from a polyoxyalkylene glycol (compound A) HO-A-OH having hydroxyl groups on both terminals thereof, and B is a group (divalent group) given by removing NCO groups from a diisocyanate (compound B) OCN—B—NCO, and (b) a recurring unit represented by the following formula (2): wherein D is a group (divalent group) given by removing OH groups from a comb-shaped diol HO-D-OH having at least two hydrocarbon groups (monovalent groups) of 4 to 21 carbon atoms in a molecule, and B is a group (divalent group) given by removing NCO groups from a diisocyanate (compound B) OCN—B—NCO, said polyurethane resin having a molar fraction of the recurring unit (a) from 0.35 to 0.99 and a molar fraction of the recurring unit (b) from 0.01 to 0.65, with the proviso that the total of both the molar fractions is 1, (ii) a solvent, and (iii) a powder selected from the group consisting of a low-melting point glass powder and a phosphor powder.
