Abstract: A novel phthalocyanine compound having improved solubility and high purity and containing a polymerizable vinyl group within its molecule is provided. Intermediates to this phthalocyanine compound also have improved solubility and high purity. Further, with the novel phthalocyanine compound used as a starting monomer, a novel polymer is obtained which has a high content of (metal) phthalocyanine and is easy to control the orientation of phthalocyanine rings. The polymer having improved solubility and high purity is expected of use as functional material such as catalysts and recording material.

Abstract: Disclosed is a small power-driven water craft of the type whose body is composed in the main of longitudinal two parts, the deck and the hull, with a standing platform in the deck at its rear portion and a stearing handle in front of the platform. In the deck at its stern side end is provided a mounting board that extends far below the bottom of the hull, adapted to permit a displaced rider to climb on board from the stern, without suffering the usual difficulty in doing so because of the imbalanced state of a craft when it is just floating in the water. In a preferred embodiment, the mounting board is slidably disposed on a sloped surface formed at the stern for movement between a raised position where the board is pulled clear out of the water and a lowered position where it stands extending at an angle into the water, conveniently for a displaced rider to grip on to its surface with his toe or knee in getting on board.
