Frank ,

I found that there was no reply to your post and wanted to help. Post thousands of posts in time , I read and answer if I could.

Your post was first to find a answer on collodion sensitizing for infrared. I am following the forum since 2006 and never saw one.

But there is red , green , panchromatic sensitizing posts , many.

May be you can learn from these posts. In my experience , patents and old books are only references.

Try to private message to Ian Grant or Photo Engineer and ask their opinion.
