Synthetic resins or natural rubbers -- part of the class 520 series

SECTION I - CLASS DEFINITION

GENERAL SUMMARY OF SUBJECT MATTER WITHIN THIS CLASS

A. The following types of claimed subject matter are proper for this class.

1. A claim drawn to a process of making a photopolymerizable composition of reactant X plus photoiniator or photosensitizer.

2. A claim drawn to a photopolymerizable composition of reactant X plus photoinitiator or photosensitizer.

3. A claim drawn to a process of irradiating reactant X with or without a photoinitiator or photosensitizer being present.

4. A claim drawn to a photopolymerizable composition of reactant X plus photoinitiator or photosensitizer and any other material (e.g., filler, solvent, etc.).

In the types of subject matter (1-4 above), reactant X can be a monomer, low molecular weight condensation or addition product, or solid polymer. The sole proviso is that the final product be a solid polymer as is required by the Class 520 Series of classes. When a claim so expressly states, a monomer or polymer is considered to be a photoinitiator or photosensitizer.
