Abstract
An organo polysiloxane to improve the abrasion and weather resistance of a hard coating layer obtained from a silicone-type hard coating composition. The hard coating composition contains a first organo polysiloxane having silicone-containing bond units selected from the group consisting of R—Si(—OX)(—O*—), R—Si(—OX)(—O*—)and R—Si(—O*—)) and a second organo polysiloxane having the same, where the second organo polysiloxane has a weight average molecular weight of 1/10 to 1/1.5 times that of the first organo polysiloxane. Further, a resin substrate having a hard coating layer made of a cured product of the hard coating composition that has improved abrasion and weather resistance. For resin substrates used in a bent state, the hard coating layer also improves the cracking resistance associated with mechanical stress.
