Abstract
Provided is a material with improved surface hardness and abrasion resistance of a plastic substrate and a process for manufacturing the same. A plastic laminate including a plastic substrate and a hard coat layer formed on the plastic substrate, wherein the hard coat layer consists of a cured film of a hard coat agent including at least a polysilazane compound and nano-silica having an average particle size of 20 to 100 nm, wherein a continuous hardness difference is provided between the plastic substrate side of the hard coat layer and the surface layer side opposite thereto.
Claims9
A plastic laminate comprising:
- a plastic substrate;
- and
- a hard coat layer formed on the plastic substrate, and having:
- a plastic substrate side facing the plastic substrate;
- and
- a surface layer side opposite to the plastic substrate side,
- wherein:
- the hard coat layer consists of a cured film of a hard coat agent comprising at least a polysilazane compound and nano-silica having an average particle size of 20 to 100 nm,
- a continuous hardness difference is provided between the plastic substrate side of the hard coat layer and the surface layer side of the hard coat layer, and
- in the hard coat layer, the surface layer side has higher hardness than the plastic substrate side.
A process for manufacturing a plastic laminate, the method comprising:
- applying a hard coat agent comprising at least a polysilazane compound and nano-silica having an average particle size of 20 to 100 nm on a plastic substrate,
- forming a hard coat layer by curing the applied hard coat agent, the hard coat layer having:
- a plastic substrate side facing the plastic substrate;
- and
- a surface layer side opposite to the plastic substrate side,
- wherein:
- in the step of forming the hard coat layer, at least by irradiating the plastic substrate applied with the hard coat agent with energy rays, a continuous hardness difference is generated between the plastic substrate side of the hard coat layer and the surface layer side of the hard coat layer, and
- in the hard coat layer, the surface layer side has higher hardness than the plastic substrate side.
