Some results obtained from the 4th test are reported herein: 1) An organo-arsenic poison compound paint has been found to be effective in preventing alga from attaching to the bottom. 2) The insoluble matrix paints were better than the soluble matrix paints as anti-fouling paints. 3) Among the samples containing organic poison and Cu2O as poisonus compounds, one containing 20% of Cu2O was subject to fouling to a greater degree. 4) In the three previous papers, sample paint No. 1 had a stable antifouling effectiveness, but in the present test it was subject to fouling to a great degree. This phenomenon suggests necessity of further study as to whether it was due to the change in the environmental conditions or due to the deterioration of anti-sea-water-defacement. 5) Hydroides norvegicus did not attach to sample paints No. 2, 3, 4 and 5. This phenomenon may be due to the effect of organo-halogenic compound poison used in common in these sample paints., 1. 有機ヒ素系毒物含有塗料は,すぐれた防藻性を示した. 2. Soluble matrix型毒物溶出機構塗料に対し,Insoluble matrix型毒物溶出機構塗料が一般防汚にすぐれていた. 3. 同種,同量の有機毒物とCu2Oとを毒物組成とする塗料で,Cu2Oの配合比が,20%のものは汚損がはげしかった. 4. 既報(3回)において,最も安定した防汚効果をしめした試料1で汚損がひどかった事は,環境条件の変化,又は耐水摩耗性能の劣化の為か検討を要する. 5. 試料2,3,4,5でカサネカンザシは付着していなかった.この事は試料に共通して含まれている有機ハロゲン系毒物の効果と思われる., 長崎大学水産学部研究報告, v.27, pp.107-113; 1969}, pages = {107--113}, title = {長崎港内における船底塗料の塗り分け試験について-4}, volume = {27}, year = {1969} }
