Abstract

An allergen reducing agent is provided that contains a terpenoid polymer or copolymer as an active component, and that functions to reduce allergens such as mites and pollen, and is capable of suppressing coloring.

Claims (12)

1. A method for reducing an allergen comprising imparting an allergen reducing function to a surface of a target where allergens need to be suppressed by applying an allergen reducing agent containing, as an active component to the surface of the target, at least one of:

a terpenoid-phenol copolymer having a structure represented by:

wherein m and n are positive intergers; or

a terpenoid-phenol copolymer having a structure represented by:

wherein m and n are positive intergers.

2. The method for reducing an allergen according to claim 1 , wherein the terpenoid-phenol copolymer has a hydroxyl number of 10 to 250 mgKOH/g.

3. The method for reducing an allergen according to claim 1 , wherein a coating material containing the allergen reducing agent and a curable resin is applied to the surface of the target and cured.

4. The method for reducing an allergen according to claim 1 , wherein the surface of the target is a surface of a wood base.

5. The method for reducing an allergen according to claim 1 , wherein the allergen reducing agent contains the terpenoid-phenol copolymer having the structure represented by:

6. The method for reducing an allergen according to claim 1 , wherein the allergen reducing agent contains the hydrogenated terpenoid-phenol copolymer having the structure represented by:

7. The method for reducing an allergen according to claim 1 , wherein the allergen reducing agent contains the terpenoid-phenol copolymer having the structure represented by:

and contains the hydrogenated terpenoid-phenol copolymer having the structure represented by:
