The paint film was irradiated with ultraviolet light (Ultraviolet 117 Aedometer K) for 48 hours and the discoloration of the paint film was investigated. The results are shown in Table 2K.

After applying K uniformly and air-drying it at room temperature for 7 days, it was placed on a flat solidified medium (potato decoction medium and inorganic salt agar medium) in advance on a petri dish, and the above-mentioned suspension of algae or mold was inoculated. The Petri dish was covered and incubated at 25°C for 28 days.
The growth status of algae and mold on the K test piece was investigated daily.

果を第4表に示す。Test Example 4 An acrylic emulsion was applied to the north exterior wall of the warehouse where algae were actively breeding. It was applied by adding 0.2, 0.5, and 1.0% by weight to the standard paint. A K inorganic salt liquid medium was sprayed on the coated surface every 30 days to promote the growth of algae, and the state of reproduction was investigated. The results are shown in Table 4.
