Patent ID: 7781555

Claim:
A microcontact printing stamp comprising a cured product of an addition reaction cure silicone rubber composition containing nonfunctional low-molecular-weight siloxane compounds D 3 to D 20 in a total content of up to 200 ppm based on the cured product, wherein the addition reaction cure silicone rubber composition comprises: (A) a linear diorganopolysiloxane containing at least two aliphatic unsaturated monovalent hydrocarbon groups in a molecule; (B) an organohydrogenpolysiloxane containing at least two silicon-bonded hydrogen atoms in a molecule; (C) an addition reaction catalyst; and (D) an organopolysiloxane resin of three-dimensional network structure containing siloxane units of R 1 3 SiO 1/2 and siloxane units of SiO 4/2 , wherein the molar ratio of R 1 3 SiO 1/2 units to SiO 4/2 units is from 0.3 to 2, and wherein R 1 is independently a substituted or unsubstituted monovalent hydrocarbon group, in an amount of 5 to 100 parts by weight per 100 parts by weight of component (A).
